PROCESS FOR PREPARING LOW PHYTATE SOY PROTEIN ISOLATE

摘要

A high quality soy protein isolate with significantly reduced aluminum content and substantially free of phytic acid and phytate complexes is prepared by aqueous extraction of defatted particulated soybeans at pH 8 to 10, and at a temperature above 65 DEG C., separating the extract and then precipitating the protein out of solution, at a pH slightly higher than its isoelectric point, i.e., pH 5.3.
